I think most people in most cultures see it as a bad thing to not thank someone for a good deed they've done you. In fact you have probably heard someone say something like this - or you've said it yourself:
"Person X is so ungrateful! I did/gave ABC for/to Person X and (s)he never even said thank you! I will not be helping Person X again!"
Is that a truly loving attitude? What is behind the desire to be thanked? Is it - should it be - a christian desire?
This OP will be a bit far out and will challenge norms of culture and courtesy that you take for granted and I'm hoping that it will also expose a bit of a contradiction in christian culture.
I think the first thing I should tackle is the question of what is behind the desire to be thanked. I think the desire to be thanked stems from the desire to be praised and recognized by others. Praise and recognition from others feeds the ego, giving you a shot of pride. So I think thanking someone is actually repaying them for their good deed, by stroking their ego and giving them a shot of pride.
Is it a good thing to expect recognition and praise for doing a good deed? Jesus condemned the action of doing good deeds in order to be praised by men. He said that good deeds done for praise will not be rewarded by his father in heaven. So how could it be a good thing to take offense at not being thanked for doing a good deed? What it actually means is that a person is taking offense at the fact that he was not given recognition, praise and a shot of pride as payment for doing a good deed.
I think there is even a subconscious recognition of the fact that being thanked is a form of praise that gives a shot of unwarranted pride. That fact is seen in the way people sometimes feel embarrassed and may blush at being thanked. It is also revealed in language. In America, persons often say, in response to being thanked: "it was nothing", "don't mention it", "no problem". What is the purpose of such expressions? It seems that the original intent behind these expressions is that the one being thanked is actually refusing the praise and recognition that he's being given by minimizing the stature of his own good deed. Of course, many people today use such expressions as a perfunctory custom without any genuine feeling behind the words. But the point is the origin of these expressions reveal an awareness of the fact that there a feeling of guilt, shame and/or embarrassment at being praised for a good deed.
So is it loving to be offended for not being thanked for a good deed? The bible says love does not brag and does not seek its own interests. The desire to be thanked is a selfish desire to be praised and recognized. True love does not seek its own interests but that of the person who is the object of the love. So if someone is giving with the expectation of being thanked - are they giving out of pure love? Wouldn't pure love be satisfied to know that the person was helped or made happy by the good deed or gift? Wouldn't that alone be reward enough without expecting to be thanked - to be praised?
And this brings me to a bible account that seems at odds with Jesus' earlier statement about not doing good to be recognized. It is the account of the blind men whose eyes Jesus opened. All of them went rejoicing at being able to see. Shouldn't that have been enough for Jesus - to see that these men are now happy and will have a better life ahead? No. For when one of them returned to thank Jesus, he bemoaned the fact that the others did not? Even Jesus, who says we should not do good for the sake of being praised by men, turned around and reproached those who did not praise him for his good deed to them, although he should have been satisfied that he had made them happy, given that his motive for helping them should be pure love and not a desire to praised for doing a good deed.
